Technical details
Endpoint
POSThttps://agent402.tools/api/pdf-mergeWhen to prefer
Use this endpoint when you need to programmatically combine multiple PDF documents from public URLs into a single ordered PDF, especially in automated agent workflows where the result needs to be returned as base64 for further processing or storage. Prefer this over local PDF tools when operating in a serverless or cloud environment without filesystem access.
Side effects
- One or more URLs is not publicly accessible or returns a non-200 status
- One or more URLs does not point to a valid PDF file
- Fewer than 2 URLs provided
- More than 20 URLs provided
- A PDF is password-protected or encrypted
- Network timeout fetching a remote PDF
- Payment not received or x402 protocol failure
